This is a highly-capable and strong chassis for your next robotics research project! Chassis components are CNC machined from aircraft aluminum. Two 37mm DC gear motors are included with encoders to enable dead-reckoning. The 2WD chassis includes a caster wheel, which allows the robot to turn freely, and minimize battery usage.
Photos show this chassis with the optional micro-switch active bumper, which can be attached the front of the chassis (not included).
